general, existing routing protocols in adhoc networks can be classified as proactive,
reactive or hybrid. Proactive protocols are table driven. Proactive protocols maintain
entire topology of network. So whenever there is routing request connection is
established quickly. Reactive protocols are also known as On-demand protocols.
On demand protocols based on fact that there is no point in maintaining network
topology since it is always changing. Hybrid protocols combines approach of
both reactive and proactive. Cluster based routing protocol (CBRP) is hybrid
routing protocol designed for MANET. By clustering nodes into groups, the
protocol efficiently minimizes flooding, traffic during route discovery.
However we have realized mobility of the nodes is not considered in route reply
process of the protocol. There is no mechanism defined for mobility of cluster
head in route reply process. In this paper we have studied existing routing
strategies in MANET and proposed a solution to the drawback we found in CBRP.
Performance of CBRP will enhanced using our proposed solution.
